Light handheld laser swinging welding head

Abstract

The invention discloses a light handheld laser swinging welding head. The light handheld laser swinging welding head comprises a collimating unit, a control unit and a light path unit, the collimatingunit is provided with a collimating connecting cylinder, the outer side wall of the circumference of the collimating connecting cylinder is a holding part, a laser incident end and a laser emergent end are oppositely arranged at the two ends of the collimating connecting cylinder, the control unit comprises a light contact switch and an induction welding nozzle, the light path unit comprises a light path main body and a swinging main body, the light path emergent end of the light path main body is bent downwards and is connected with a welding head body, the light path incident end of the light path main body is horizontally connected with the laser emergent end, and the swinging main body is arranged in a mode of extending upwards in the direction away from the outer end surface of the light path incident end. According to the light handheld laser swinging welding head, a swinging motor is arranged to control the angle of a reflecting lens in real time, and the laser light path is adjusted, so that the width of a weld joint is adjusted, the width of the weld joint is increased, then a product is not prone to weld penetration, and the welding efficiency and the welding quality areimproved.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a light hand-held laser swing welding head. Background technique [0002] The laser welding head is a kind of laser external light path equipment. The optical fiber is connected to the laser, and the internal optical lens adjusts the collimation and focus of the laser, and is monitored and operated by the control system. Laser welding, as an advanced welding technology, has been widely used in electronics, automobiles and other industries with the help of automatic control systems. At present, manual welding in the market is argon arc welding, manual welding or ordinary laser welding, while argon welding Arc welding and manual welding have relatively high requirements for operators, and are more likely to have problems in terms of safety. (The original argon arc welding and manual welding are harmful to the human body, and you need to hold a special operation certificate ...

Problems solved by technology

Laser welding, as an advanced welding technology, has been widely used in electronics, automobiles and other industries with the help of automatic control systems. At present, manual welding in the market is argon arc welding, manual welding or ordinary laser welding, while argon welding Arc welding and manual welding have relatively high requirements for operators, and are more likely to have problems in terms of safety.

(The original argon arc welding and manual welding are harmful to the human body, and you need to hold a special operation certificate to work on the job.) At present, the few hand-held laser welding that can be used on the market have relatively few common applications, and are not easy to operate. It is easy to weld through the product, the weld seam requirement is relatively small, and it cannot be adjusted
